Abstract: Applicants: Richard A. Blincoe and Louis C. Hrusch Title:       "Dual Cylinder Linear Servo Motor"                         ABSTRACT OF THE DISCLOSURE Servoactuator includes a pair of double-acting linear actuators providing for 360° controlled rotation of an output shaft. The rotary motion of the output shaft is employed to sequence high pressure fluid flow and return for the same to the respective ends of the respective actuators so that both actuators continuously develop output force except for end stroke points. Shimmy damping may also be obtained by a bypass-damping valve which comprises a shuttle movable to a first position by high pressure fluid for controlled operation of the servoactuator and to a second position by removal of the high pressure fluid to direct fluid flow between the respective actuators through a damping orifice.

Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a process, devices and taximeters for avoiding fraud on the price indicated by the luminous display means of an electronic taximeter, wherein a taximeter comprising a luminous display means and a computing unit is supplied with d.c. voltage V by the battery of the vehicle. A comparator compares the voltage V with a reference voltage Vr and emits a constant voltage Vc if V < Vr and a zero voltage if V > Vr. A device compares the dura-tion during which V remains lower than Vr with a reference duration and returns the computing unit and the display means to zero each time the reference duration is exceeded. One application of the invention is the construction of electronic taximeters which are difficult to use fraudulently.

Abstract: 5. Das, et al 5-4-1 Abstract of the Disclosure An apparatus and method of organizing line interface modules between analog subscriber lines/trunks and a digital switch with the provision for ringing signals which may be shared by a plurality of lines from a single source is described.  The ringing signals are intercoupled to any line or lines and transmitted through a common metallic bus which provides immediate ringing for any line, with a shared ring-trip circuit.  A software-controlled and/or programmable signal generator in combination with a novel ring-trip circuit is described wherein ringing cadence is generated by connecting the programmable signal generator to a subscriber line for the proper duration and at any desired frequency, whereby multi-frequency ringing can be accomplished under programmable control. A spare line control function within a cluster of tele-communications line circuits is provided such that any telecommunications line circuit can arbitrarily be desig-nated as a spare line, usable to provide temporary service, for example, to a telephone subscriber having a defective line, thereby permitting scheduled maintenance rather than on-demand maintenance,.  Immediate ringing is provided to groups of analog telephone lines having shared ringing sources and shared ring-trip circuits in a system architecture compatible with a digital switching system.

Abstract: ABSTRACT OF THE DISCLOSURE         A heating apparatus in which an object to be heated placed in its heating chamber can be heated until the surface of the object is charred as desired by the user.  A first photo sensor senses the intensity of light of visible spectrum range directed toward and reflected from the surface of the object being heated, and a second photo sensor senses the light intensity related to the light reflected from the surface of the object, that is, at least one of the intensity of illuminating light emitted from a light source and the intensity of illuminat-ing light coming from the exterior of the heating chamber.          The degree of charring of the surface of the object is judged on the basis of the output signals from the first and second photo sensors, and the heating operation is controlled on the basis of the result of judgement.

Abstract: HEAT COLLAPSING FOAM SYSTEM            ABSTRACT OF THE DISCLOSURE     A process of treating sheet materials with an aqueous treating com-position is disclosed in which surfactants are incorporated in the com-position to permit it to be foamed with gas to provide a foam which is stable in the form of a thin layer long enough to be handled, but which will collapse completely when heated.  This is preferably done by em-ploying a mixture of water soluble surfactant to stabilize the foam and water insoluble defoamer to break the foam when heat is applied.  This foam is applied to a surface of the sheet material to provide stable foam thereon, and heat is employed to simultaneously cause the foam to collapse and dry the composition.
